Romans 10:10

With the heart one believes unto righteousness, and with the mouth confession is made unto salvation.

We have a part to play in our relationship with God.  It all began by believing in our hearts and confessing for our salvation.  Our believing and speaking words of faith didn’t stop the day we were saved.  It was just the start.  Salvation and righteousness were the first steps of faith into the Kingdom of God.  We are to keep believing and speaking words of faith and developing in God’s word.
